Abstract: PURPOSE:To adapt an electrophotographic sensitive body to a printer using a laser as a light source and to enhance sensitivity by incorporating a phthalocyanine pigment in an electrostatic charge generating layer and using an acrylic resin as a binder for a charge transfer layer. CONSTITUTION:The phthalocyanine pigment is incorporated in the charge generating layer of a photosensitive layer of a functionally separated laminate structure, and the charge transfer layer contains as a binder one or more kinds of acrylic resins represented by the formula in which R1 is H or methyl; R2 is a 1-4C satd. alkyl, aromatic, or naphthenic group, and H of these group may be substd. by Cl or F; and n is a value capable of forming a solid polymer. The incorporation of the phthalocyanine pigment sensitive to semiconductor laser beams and the use of the acrylic resin for the binder of the charge transfer layer to be formed on the charge generating layer change configuration of molecules in the interlayer between both layers and the level of a barrier, affect sensitivity and photomemory, and permit a photosensitive body superior in sensitivity and small in PM to be obtained, charging to be specified, and an image good in quality to be formed. As a result, the obtained photosensitive body has high sensitivity and can be used for electrophotography using semiconductor laser beams as the light source.
